Description
This vacuum pressure impregnation machine is mainly application of insulation processing for electrical products, such as high voltage motor, generator, H class dry type transformer, power capacitor, cable insulation, and motor repairing, etc.
For example, coil windings of motor or transformer can be evaporated at vacuum condition to reduce influence from moisture, air or other impurities. With pressure impregnation, resin can be immersed into inner side to make the high insulation class. VPI equipment is also used in material industry for improving material performance.

Features
1. Integrated pressure vessel, vacuum, pressurization, cooling, heating and automatic controlling
2. PLC controlling and touch screen operating
3. Equipped with safety alarm and interlock protection device

Work Process of Vacuum Pressure Impregnation Machine
The workpiece will be load and put into the VPI tank, under vacuum to remove the traces of water and gas in the workpiece, and then through the pressure difference to feed the resin material into VPI tank. Under certain pressure to make immersion inside of the workpiece to achieve complete impregnation. After impregnating the resin material will return to storage tank by pressure. The products will be draining and then unload from the VPI tank.
